Parameter Comparison

Engineering Selection Recommendations

Both the WR-PHD 61301421821 and RS2-14-G are active production parts with ROHS3 compliance and REACH unaffected status, qualifying them for use in regulated applications. The parts share identical electrical ratings (3A current, 250VAC voltage) and mechanical configurations (14 positions, 2.54mm pitch, through-hole solder termination).

The primary distinction between these parts is the operating temperature range. The WR-PHD 61301421821 operates to 125°C, while the RS2-14-G operates to 105°C. Applications requiring sustained operation above 105°C must use the WR-PHD 61301421821. For applications with maximum operating temperatures at or below 105°C, both parts are functionally equivalent.

Minor dimensional variations exist in insulation height (0.331" versus 0.335") and contact post length (0.122" versus 0.118"), which remain within acceptable tolerances for standard board-to-board connector applications. The RS2-14-G uses glass-filled PBT insulation material compared to standard PBT in the WR-PHD 61301421821, providing enhanced mechanical properties without affecting electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the RS2-14-G directly replace the WR-PHD 61301421821 in all applications?

A: The RS2-14-G is a direct mechanical and electrical substitute for applications operating at temperatures up to 105°C. Applications requiring operation above 105°C must use the WR-PHD 61301421821 due to its extended temperature rating to 125°C.

Q: Are the dimensional differences between these connectors significant?

A: The dimensional variations (insulation height difference of 0.011" and contact post length difference of 0.004") are within standard manufacturing tolerances for rectangular connectors and do not affect compatibility in standard board-to-board applications.

Q: What is the difference between the contact materials used in these parts?

A: The WR-PHD 61301421821 uses copper alloy contacts while the RS2-14-G uses brass contacts. Both materials provide equivalent electrical conductivity and corrosion resistance when combined with gold plating. The choice between them does not affect connector performance in standard applications.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the WR-PHD 61301421821 and RS2-14-G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in regulated markets.

Q: What is the significance of glass-filled PBT insulation in the RS2-14-G?

A: Glass-filled PBT provides enhanced mechanical strength and dimensional stability compared to standard PBT. This material enhancement does not affect electrical performance and may provide improved durability in applications subject to mechanical stress or vibration.

Q: Are there inventory considerations when selecting between these parts?

A: The WR-PHD 61301421821 maintains 905 pieces in stock while the RS2-14-G maintains 2173 pieces in stock. Availability may influence component selection based on project timelines and procurement requirements.
